THILL=COUPLING.

SPECIPTCATION forming part of Letters Patent No. 364,032, dated May 31, 1887.

Application filed December 3, 1886. Serial No. 220,605. (No model.)

To all whom it may concern:

Be it known that we, PETER T. MOMILLAN and HALLET T. HILL, of Bay Shore, in the county of Suffolk and State of New York,

haveinvented a new and Improved Thill- Coupling, of which the following is a full,

clear, and exact description.

'Our invention consists of a thill-coupling eye made in sections to adapt the thill to be connected to the jack clip without removing the clip bolt or pin.

The invention also consists of a thill-coupling eye made in sections combined with the jack-clip and its bar, the latter serving as a lock to the lower section of the clip when the thills are lowered to position for use.

The invention finally consists of the employment of rubber packing within the sectional eye and of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this-specification,

in which similar letters ot'refcrence indicate corresponding parts in all the figures.

Figure 1 shows our new and improved thillcoupling in side view applied to an axle and curved end of a thill, the latter being in the position it assumes when the thills are held in the thill-loops of a harness. Fig. 2 is a sectional elevation of the curved end of the thill, the coupling, and the axle, the thill being shown in elevated position for detachment from the clip; and Fig. 3 is an inverted view of the axle jack-clip and eye.

A represents the axle, and B the jack-clip, which is formed with the cheek-pieces a a and pin 1), and attached to the axle by the crosspiece (I, which is slightly projected at its for ward end, (2, to stand near or in contact with the thill'eye G. The eye 0 is sectional or made of two parts, the main part f formed integral with the thill-iron D,and the removable section f connected to the thill-iron 'D by ascrew, f and nut.

About the screwf the iron D is made flat, as shown at i, to form a seat for the front end of the section f, which is elongated and formed with an aperture, j, for the screw f Upon the pin Z) is placed the annular packing E, of rubber, which is compressed by the attachment of the section f, and prevents rattling.

The rear meeting-edges of thesectionsff' and the seat 2' are ina plane with a diameter of the eye and at an angle with the plane of the axle, so that when the thills are in the position shown in Fig. l the lower joint, f will come within the area of the curved surface d of the cross-bar d of the clip, so that the bar acts as a safeguard to obviate all danger of the seetionf' becoming accidentally detached. When the thills are raised to the position shown in Fig. 2, the jointf is carried in front of the bar d, so that the section f may be easily removed f, bolted together, in combination with the clip A, pin b, packing E, and the bar d of the clip. which serves as a lock to the section f of the clip, substantially as described.
